Detailed information on this topic can be obtained at your local Hilti Center.
3.6 Active Torque Control
The tool is equipped with a mechanical slip clutch and an Active Torque
Control (ATC) system.
This system provides additional drilling safety and convenience as it causes
rapid shutdown upon sudden rotation of the power tool about the drill bit
axis. This may occur, for example, when the drill bit sticks due to hitting a
rebar or when the drill bit is tilted unintentionally.
Always choose a working position in which the body of the power tool,
when running in a forward direction (clockwise), is free to rotate in a
counterclockwise direction (as seen by the operator). When running in
reverse, the tool reacts to sudden clockwise rotation. If rotational movement
is not possible, the ATC system cannot react.
3.7 Active Vibration Reduction
The tool is equipped with an Active Vibration Reduction (AVR) system which
reduces vibration noticeably.
3.8 Quick-release chuck (accessory)
The quick-release chuck makes it possible to change accessory tools
quickly, without need for a chuck key (keyless system). It is suitable for
accessory tools with a cylindrical or hexagonal shank, such as drill bits for
wood and metal, or mixing paddles, which are used in the rotary-only mode
(without hammering action) .
